Definitions

  • the present invention relates to a method for laminating disc-shaped substrates, more particularly to such a method of integrally laminating two disc-shaped substrates using an adhesive sheet, and more specifically to such a method for laminating both the two disc-shaped substrates together as a unit.
  • an optical disc so called “DVD” a disc-shaped substrate in the form of single plate which constitutes it is standardized as a thickness of 0.6mm, an outer diameter of 120mm, and an inner diameter 15mm in its central hole.
  • the disc-shaped substrates each of the same thickness are bonded onto each other to form an integrated substrate in a practical use thereof.
  • Such a high density storage disc-shaped i.e. a DVD
  • a high density storage disc-shaped is generally used as a ply-plate structure as set forth above, but is not used as a single plate. In such a case, it is necessary that both the upper and lower disc-shaped substrates to be bonded onto each other.
  • UV cured resin as the adhesive agent is coated to the lower disc-shaped substrate in the form of a doughnut, with the upper disc-shaped substrate being placed thereupon to rotate both the disc-shaped substrates to thereby develop or draw the UV cured resin.
  • UV cured resin interposed between both the disc-shaped substrates together as a unit.
  • a step or the like of irradiating UV for curing the adhesive agent is required to thus increase manufacturing processes thus increasing manufacturing cost.
  • an adhesive sheet member is employed instead of UV cured resin (adhesive agent).
  • this is such a method that the adhesive agent as an adhesive sheet member is bonded to the lower disc-shaped substrate, with the upper disc-shaped substrate being overlaid thereon, and that these disc-shaped substrates are pressurized by a pressing body from above to integrate them as a unit.
  • EP-A-0 854 477 discloses a method according to the preamble of claim 1.
  • an adhesive sheet with the adhesive agent applied thereto is pressed against the disc-shaped substrates from one end to the other end in a step of bonding the adhesive agent to the surface of the lower disc-shaped substrate in such a manner that the adhesive-backed sheet is pressed against the substrate.
  • the pressing body is so held against the upper disc-shaped substrate as to magnify a contact portion from the center side to the outside in a step of pressing the upper disc-shaped substrate against the lower disc-shaped substrate by means of a pressing body in a state whereas the pressing body is held against in such a manner that a contact portion may be magnified from the center side to the outside.
  • a method of laminating disc-shaped substrates according to the present invention is characterized in that two disc-shaped substrates are bonded together by an adhesive agent to leave or expose them to the high-pressure atmosphere for a certain time.
  • Figs. 1 through 4 are views showing how to laminate the disc-shaped substrates through the method according the present invention.
  • the lower disc-shaped substrate D1 is held in such a state where it is laid on a holding table 2.
  • an adhesive sheet body S is supported between each of tension rollers 5A and tension rollers 5B disposed upstream and downstream the holding table 2 and a laminating roller 1 under condition where a sheet like adhesive agent S2 in the form of a doughnut is downwardly exposed underneath of the sheet body S.
  • a pitch feed roller 6 and a take-up roller 7 are arranged forwardly and outwardly of rollers 5A and 5B.
  • a centering shaft 3 as a positioning member is lowered to position the adhesive sheet body S with respect to the lower disc-shaped substrate D1 for the adhesive sheet body S.
  • suction is made in a small hole (not shown) perforated through the holding table 2 so that the lower disc-shaped substrate D1 may be sucked and held so as not to move as it is positioned on the holding table 2.
  • a pressure roller 1 as a hold down member (as shown in Fig. 3) is rolled upwardly over the lower disc-shaped substrate D1 (more specifically, over the adhesive sheet S on the lower disc-shaped substrate) in the direction of an arrow in Fig. 3.
  • centering shaft 3 is move upwardly in the phase where rolling motion is initiated) and is kept away therefrom.
  • the adhesive sheet member S is pressed against the lower disc-shaped substrate D1 to press the adhesive sheet member S against thereby sticking it to all over the surface of the lower disc-shaped substrate D1.
  • Pressure derived from the pressure roller when rolled may be enough to provide contact pressure (normally, 2 3 atmospheres or so) to the extent that the adhesive sheet member may be stuck to the surface of the lower disc-shaped substrate.
  • Release member (Fig. 4) as means for peeling off, which is disposed downstream of the holding table 2 is quickly so moved as to traverse between the adhesive sheet S and the lower disc-shaped disc substrate D1 laid on the holding table.
  • the surface of the lower disc-shaped disc substrate D1 is peeled from the adhesive sheet member S (more particularly, a carrier S1).
  • the adhesive sheet member S is peeled from the lower disc-shaped disc substrate D1 (more specifically, an adhesive agent S2 on the lower disc-shaped disc substrate) to make free therefrom at the time when the release member 4 have completed to traverse the holding table D1.
  • the adhesive sheet member S (more particularly, carrier 1) is peeled off from the lower disc-shaped disc substrate D1 to then afford the state where the adhesive agent S2 is applied to outwardly of the upper disc-shaped substrate (see Fig. 10).
  • a first station Z1 which is a station where the adhesive agent S2 is applied to the lower disc-shaped disc substrate, as explained hereinbefore, is then moved to a next station, that is, a second station Z2 (see Fig. 5).
  • a pressing body 100 is pressed from above against the both disc - shaped substrates D1, D2 placed on the holding table.
  • Fig. 8 shows the instance where the pressure plate 100 is pressed against both the disc-shaped substrates (namely, the upper disc-shaped substrate) contrary thereto, it is possible to lower the pressing body to have consequently pressurized both the disc-shaped substrates.
  • the pressing body may be fabricated of flexible material in a hemispheric form and provides pressure force to allow the upper disc - shaped substrate D2 to pressure against the lower disc-shaped substrate.
  • Pressing action in this case results in that the pressing body is permitted to press against the disc-shaped substrates to so enlarge or magnify the contact portion from the center side to the outside as to function to squeeze air bubbles between both the disc-shaped substrates outwardly.
  • the two disc - shaped substrates D1, D2, for the time being, are bonded to each other.
  • Both the disc-shaped substrates D1, D2 as laminated to each other are moved to a fourth station Z4 (see Fig. 5).
  • both the disc-shaped substrates set on the holding table are so covered by an outer wall member as to enter into a pressure container with a closed air space.
  • Fig. 8 is a schematic view for use to explain a high-pressure atmospheric condition (pressurized condition) provided by use of a high-pressure container.
  • a condensed air is fed through a flow route pipe 8 space 80 closed by the outer wall member of the high-pressure container to thereby afford the predetermined high-pressure.
  • the pressure of the high-pressure atmosphere may be freely adjusted. In this instance, after both the disc-shaped substrates D1, D are entered within the high-pressure container 8, a pressure is increased in the space 80 therein as sealed and so conditioned to obtain the high-pressure atmosphere as set.
  • Air bubbles are between the two disc-shaped substrates D1, D2 left to the high-pressure atmosphere are reduced in size to minimize them to a great extent or mostly disappeared.
  • Fig. 9 illustrates the aforementioned principle in a typical form.
  • Fig. 9A shows a condition under which both the disc-shaped substrates D1, D2 seal the air bubbles 9 before they are left to the inside of the high-pressure atmosphere.
  • Fig. 9B shows a condition under which both the disc-shaped substrates are left within the high-pressure atmosphere. At this moment, the volume each of the air bubbles is reduced to show Dimensions V1 ⁇ V2 (V1>V2) thus well balanced where the adhesive agent S2 is firmly mounted to the disc-shaped substrates together.
  • pressure of the high-pressure atmosphere should be more than the pressure applied to the both disc-shaped substrates D1, D2 before the instant step.
  • Both the disc-shaped substrates are exposed or subject to pressure greater than such pressure as applied to the step prior to the instant step to thereby decrease the air bubbles so that the adhesive agent is firmly secured to both the disc-shaped substrates after a lapse of a certain time. Both the disc-shaped substrates keep securable.
  • pressure may be equally applied between both the disc-shaped substrates so that pressure may be also applied in the same manner as aforementioned to the air bubbles dispersedly contained in the adhesive agent there between.
  • the air bubbles in both the whole disc-shaped substrates may be impartially and averagely to have them reduced.
  • Variation in each of the air bubbles is proportional to pressure applied between both the disc-shaped D1, D2 so that such pressure is enough to the extent that each of the air bubbles may be so sized as to provide the optical disc from the quality point of view.
  • each of the air bubbles may be standardized as 50 ⁇
  • the maximum dimension of each of a multiple of the air bubbles should be set to be less than 50 ⁇ .
  • both the disc-shaped substrates left to the inside of the high-pressure atmosphere for a certain time of period result in an optical disc D of a high quality, which minimize or eliminate the air bubbles, to the utmost, between the substrates (see Fig. 11).
  • the air bubbles may be minimized or eliminated to the full extent by leaving the discs inside of the high-pressure atmosphere for a certain time of period.
  • the pressure member is employed in advance to press the upper disc-shaped substrate against the lower disc-shaped substrate to increase to improve the result prior to be the atmosphere as highly pressured.
  • Figs. 12A and 12B illustrate a step in which the upper disc-shaped substrate is beforehand pressed by the pressure member prior to leaving the same inside of the high-pressure atmosphere.
  • Fig. 12A shows the condition of the high-pressure container before having it high pressurized.
  • Fig. 12B shows the condition under which the upper disc-shaped substrate is pressed by the press member. For information, this is the case where pressure action is performed by upward movement of the holding table.
  • the holding table is machined and the press member is then non-contact condition to have high-pressurized.
  • the press member used herein may be flexible and substantially hemispheric form as shown.
  • the press member may be pressed against the disc - shaped substrates to enlarge the contact portion from the central side to the outside to so act the air bubbles as to push out outwardly (radially).
  • pressure derived from the flexible pressure member may more increase the central portion than the peripheral portion to bias pressure applied both the disc-shaped substrates.
  • the pressure force which relies on the press member may not contribute to reduction in the air bubbles.
  • stations Z1, Z2, Z3, and Z4 are explained when they are in the same table, it is possible to apply pressure force other position than those on the turn table.
  • a space which produces the high-pressure atmosphere may preferably provide another position.
  • steps in the stations Z2 and Z3 may be carried out in the same position.
  • each of the air bubbles may be reduced by simply performing reduction in the high - pressure atmosphere in the conventional step.
